Interesting set of options Apple has to move the iPhone to a 4" display, as detailed by Dan Provost. I don't care how Apple does it, as long as they do it. The iPhone's tiny screen is nearly unusable once I got used to the 4.3" of my HD7 and SII. This is quite a personal choice, of course, and there's no right or wrong, but it's clear there is a demand for larger displays.

Apple releases a 4" phone, everyone then complains that it should have been 4.3" personally for me 3.5 is fine, keeps the phone small enough without sacrifices text/image quality. I don't think I've ever looked at my iPhone and wished the screen bigger. I don't know if this is because i also own an iPad and switch between them when i need to look at large amounts of content.

I consider the iPhone a mobile device, something thats small and easily carried the trade off for this is screen size. Ive tried 4" and 4.3" and a lot of them are simply too big. Adding a larger screen is really only going to affect the spec sheet, i don't think it will add that much to a mobile device.

I have a 5.3" mobile phone and I have never really seen a point in having a smaller phone. Movies are simply awesome (I actually prefer it compared to my shitty laptop screen), internet experience very good (no need to zoom in landscape mode), PDF reading perfect (again, no need to zoom in landscape), gaming very good, and all that without a slightest compromise in mobility or comfort.

I don't understand this. The screen is still absolutely tiny compared to anything good. A phone is crappy for movies, no matter what. Yes I've watched movies on my phone and it's fine in a pinch, but I don't see how an extra inch would make any difference whatsoever. When I want to watch a movie, I watch it on the projector, which is about 150 times as big.

and all that without a slightest compromise in mobility or comfort.

Well, some compromise in mobility since it's quite a bit larger.

More importantly for me, massive compromise in battery life. Browsing battery life in both the big screen phones is absolutely atrocious. The iPhone lasts over twice as long.

Personally, my big problem with the iPhone is that it does not use as much of the device size as it can. Even with the same physical dimensions the screen could be bigger and a bigger screen would be very welcome. I think that the "retina" resolution is even high enough to support the larger size without a noticeable loss of quality.

Of course, they have kind of painted themselves into a corner with the way they handle resolution. As it stands now, they need to expand the number of pixels by some even multiplier in order to support increasing the screen size without distortion.
